We upgraded our IP Office system to the latest firmware about 3 months ago. We continue to have issues with the system, post-upgrade.
Issue #1
Primarily, our CID does not display correctly anymore. We now see "External" about 50% of the time on incoming calls. This started happening the morning after our upgrade to 4.12.
Issue #2
We randomly get an Error "8kHz clock source changed. Previous source was internal".

Aside from these issues, I do have a few questions as well:
In the call monitor software we can look at line utilization, active calls, etc... It appears as though incoming calls are placed on channels 1-12 and outgoing calls are put on channels 13 - 23. If all channels of the PRI are in use, what happens to incoming calls? Is there a way to prioritize calls so that INCOMING calls get priority over outgoing calls? We are looking to install another PRI and have 2 total with 46 channels available. Our Control Unit Module shows Port A and Port B (port A has a T1 and Port B is empty). Can Port B be equipped with another T1 module to handle the 2nd PRI or would we be forced to get a totally different Control Unit?
Thanks so much for your time and love the fact that this forum is available for the end user. Our Avaya support "team" is not always responsive and most of the time has very ambiguous answers that appear to indicate they themselves do not really know the answers either

1: Most likely the channels are programmed for T1 not PRI.
2: I personnaly do not know what this is caused by.
3: When all the channels are in use, callers get a busy tone unless you have an external telco voice mail.
4: I don't beleive you can "prioritize" inbound over outbound. All you can do is reduce the number of channels in the ARS pool.

It sounds as though you describe an IP 400, not 500 (Slot A and B). If you do have the 400, you must either replace the single PRI card with a Dual PRI or just add another single PRI card to Slot B.

Send me a copy of your config. The T1 may not be set up correctly.

The IP office ca not say that calls only go out channels 13-24. BUT, the T1 should be set up as either Ascending or Descending, whichever is the opposite of the T1 provider. That is done so if the LEC presents a call at the same time the IP Office requests dialtone, there is going to be a channel overlap.

What version firmware did you have on the unit previously? Are you a vendor? Did you upgrade the unit as per the tech tips? And, what hardware are you using?

My apologies. It is an IP 400, not 500. We are on currently running 4.12 firmware. Previous to the upgrade, we were running 3.0 (i think. I know it was 3. something). We upgraded the configuration because our call forwarding was not working un the old firmware. Call forwarding to an outside number works GREAT now, but we took 2 steps backwards. Thanks again for any additional insight you might have

I am not a vendor. I am the new network admin for this company. THe upgrade was performed by our Avaya vendor. Hardware is as follows, Control Unit = IP406 V2 DS (fw v 4.1(12))
DS16 v2, firmware v6.1
Phone8 v2, fw v6.1
DS30 v2, fw v6.1
All desktop phones are 5410 or 5420. All phones were upgraded during the process as well. Please let me know anything else I can provide

Issue 1: may be a configuration problem like Mongo said, or you have more callers with caller id blocked, or your provider changed something.

Issue 2: isn't really an error, it is simply letting you know that the system is getting timing from the DS1 circuit which is what you want.

I would agree with you about the callers with CID blocked, except that the correct information shows in the call monitor and system status active call information. It shows as "external" on the agents phones. I have added LONGER_NAMES to the NoUser to allow all information to be displayed in the CID field, just incase the information is too long for the CID field. I checked the channel configuration and they appear to be allocated for PRI. I just think this is funny that is happened when the system was upgraded. We were told not to get f/w v.4.0 as is was "flakey". So we went from v.3.x to 4.1. Thanks again for any help and assistance you can give.

That may be the problem. I always go through the releases. 4.0 had bugs, but I still go from 3.2 to 4.0.5, then up to the highest maintenance release, before going to 4.1......
